DSMS Piston rods

Piston rods will be reconditioned according to hard surface treatment. While others used the method of metal spray or welding the piston rod with harder material, we weld the piston rod with original material and do a hard surface treatment afterwards. This will minor the chance to get small haircracks like you can have when you weld with a harder material. Hardness of an piston rod is around 280 brinell while our method will result in a hardness of 300 brinell.
